  • Valve unit and reaction apparatus having the same
    Patent number: 8499793
    Abstract: Provided are a valve unit and a reaction apparatus having the valve unit. The valve unit includes a phase transition material, which melts and expands upon an application of the electromagnetic waves to the valve filler, and the valve filler is directed into the channel through the connection passage and closes the channel. The valve unit also includes heat generation particles, which are dispersed in the phase transition material and generate heat upon an application of electromagnetic wave energy.
    Type: Grant
    Filed: December 27, 2010
    Date of Patent: August 6, 2013
    Assignee: Samsung Electronics Co., Ltd.
    Inventors: Jong-myeon Park, Yoon-kyuong Cho, Jeong-gun Lee, Beom-seok Lee, Sung-woo Hong
